Sounds like --write-batch will do what you want.  Assuming you are using
rsync 2.6.3 (I would not recommend earlier rsync's batch support).  So
run this on h2:

    cd /tmp
    rsync -av --write-batch=foo h1:/src/ /dest/

Or _alternately_, this on h1:

    cd /tmp
    rsync -av --write-batch=foo /src/ h2:/dest/

Then, burn /tmp/foo and /tmp/foo.sh onto DVD and take it to h3 and run
this:

    cd /mnt/dvdrom
    ./foo.sh

Or, if you need a different dest, this:

    cd /mnt/dvdrom
    ./foo.sh /different/dest/

That's the simple version.  You aren't required to use the foo.sh file
if you want to run the appropriate --read-batch=foo command yourself on
h3.
